[Ifeffit] "Hard tests failed in fovrg"

Hi all,   I am trying to fit Eu L3 edge EXAFS data of Eu complex whose structure is known (hopefully correct). The default feff6l in Artemis reports an error  “Hard tests failed in fovrg. Muffin-tin radius may be too large; coordination number too small“. When I run feff8.2, this error exchanges

[Ifeffit] Self absorption Correction

Hi there, I have measured a pure reference compound with high absorber concentration in fluorescence mode (P K-edge XANES). I tried to use the Self absorption correction included in Athena but I don't really understand the results. Fist: Do I have to use the edge step normalized spectrum or t
